Název v původním jazyce

Review of Langmuir-wave-caused dips and charge-exchange-caused dips in spectral lines from plasmas and their applications

Popis výsledku v původním jazyce

We review studies of two kinds of dips in spectral line profiles emitted by plasmas: Langmuir-wave-caused dips (L-dips) and charge-exchange-caused dips (X-dips). L-dips are a multi-frequency resonance phenomenon caused by a singlefrequency (monochromatic) electric field. X-dips are due to charge exchange at anticrossings of terms of a diatomic quasi-molecule, whose nuclei have different charges. As for practical applications, observations of L-dips constitute a very accurate method to measure the electron density in plasmas and allow measuring the amplitude of the electric field of Langmuir waves. Observations of X-dips provide an opportunity to determine rate coefficient of charge exchange between multi-charged ions. This information is important formagnetic fusion in Tokamaks, for population inversion in the soft x-ray and VUV ranges, for ion storage devices, as well as for astrophysics (e.g., for the solar plasma and for determining the physical state of planetary nebulae).
